There are some reports that users are running into an error after installing this profile:

"This request was aborted because it appears to be forged."

We haven't figured out exactly what the problem is or how to fix it (haven't yet been able to duplicate it here), but think it's got something to do with recent CSRF security additions to ProcessWire.

If you get this error, you may want to use the default profile instead (at least until there is a newer version of this blank profile). You can essentially get to a blank profile by deleting the few pages, templates and fields that are included with the default profile. Though many users find them to be a good starting point as they are.

I am with Evan, please update the instructions to reflect the location of the directory replacements to SITE-DEFAULT. Being a super newb to processwire, I spent several hours perusing the forums trying to figure it out before I post a question.
